The Negatives of Seeing Only What you Want to See

Marketers are trying to create an electronic world where you will only see what you want. They want to send you ads that you're interested in and avoid annoying or ignored messages. To achieve this, marketers are collecting data and trying to map your interests, even by watching your eyes. The danger is that this trend will extend beyond advertising and into the domain of news and broader information, leading to people being isolated in their exposure to the external world.
